The present invention is directed to the provision of small molecule inhibitors of the PSD-95/NMDA receptor interaction, employing an undecapeptide corresponding to the C-terminal of the NMDA as a template for finding lead candidates. A compound (NMDAR/PSD-95 inhibitor) of the invention includes a peptide or peptide analogue comprising at least four peptide bonded residues having the sequence YTXV or YSXV, wherein Y is selected from among E, Q, and A, or an analogue thereof and X is selected from among A, Q, D, N, N-Me-A, N-Me-Q, N-Me-D, and N-Me-N or an analogue thereof, wherein an amino-terminal residue of the peptide is N-alkylated. Alternatively the compound of the invention comprises a first peptide or peptide analogue linked to a second peptide or peptide analogue by a linker, where the first and second peptide or peptide analogue each comprise at least four peptide bonded residues having the sequence YTXV or YSXV, wherein Y is selected from among E, Q, and A, or an analogue thereof, and X is selected from among A, Q, D, N, N-Me-A, N-Me-Q, N-Me-D, and N-Me-N or an analogue thereof.
本发明旨在提供PSD-95/NMDA受体相互作用的小分子抑制剂,利用与NMDA的C端对应的十一肽作为寻找先导候选物的模板。本发明的化合物(NMDAR/PSD-95抑制剂)包括至少含有序列YTXV或YSXV的四个肽键残基的肽或肽类似物,其中Y从E、Q和A中选择,或其类似物,X从A、Q、D、N、N-Me-A、N-Me-Q、N-Me-D和N-Me-N中选择,或其类似物,其中肽的氨基末端残基是N-烷基化的。或者,本发明的化合物包括第一肽或肽类似物通过连接物连接到第二肽或肽类似物,其中第一和第二肽或肽类似物各自至少含有序列YTXV或YSXV的四个肽键残基,其中Y从E、Q和A中选择,或其类似物,X从A、Q、D、N、N-Me-A、N-Me-Q、N-Me-D和N-Me-N中选择,或其类似物。
